Ok I will start by saying I found my cat was plugged....Ok! that was fixed Cough Cough! Ran much better now...Ok now for the 2nd O2. Started looking at ways to fool the sensor..Did some research on it and found a couple ways..I don't know what is right or wrong..I'm a try it and see kinda guy sometimes... So if you buy a spark plug non fouler dorman 42009 at advance.( Same Thread as O2) Take it drill it out to 1/2 on the inside of it then install in the rear. Suppose to take it out of the stream enough that it just reads enough to work...I don't know if it works or not for sure. I can say that when I did that that it idled ruff and was acting all weird like it had a bad throttle position sensor... So I was messing around with it tonight and seen my fuel pressure was looking high..Like 65psi....Took and adjusted it down and it started running worse...Go figure! So I said heck with it and started turning it up and wala the miss went away. Now did the miss go away it is unreal the crispness of the throttle! Rediculously better! I mean WOW! Woke it up!!!! Can't wait to run it on the hills! So who knows but I do know this is the best by far that it has ran since I got it!

Chime in! I just wished I had a way to compare it to another one!

Ok well Going away over the weekend but I will be checking for updates! Have a Great Memorial day! Oh yeah check out Templeton Pa of Youtube....I gotta go there...Someone here is from there but it escapes me at this moment of who...LOL Sorry....

      Please help 2021 Axis 750 crew won't shift into gear and found milky oil on inspection
      By BMurph
      Hello everyone! I am new here and have no experience with UTVs but I am quickly getting some. I have a shifting problem where I can shift through all gears without the engine running but as soon as I start the engine I can not select a gear. Yes, foot is on the brake and yes the pin is being pulled to go into reverse if I was to try going into reverse. The shift lever does not move. I adjusted the linkage to get more accurate shifting with the engine off so I know those are now correct. I opened the shift lever housing to inspect the teeth on the gear and found this picture below. Why is this oil so milky looking? I assume with oil like this I'll need to replace the wet clutch as well but am not positive. Does anyone have any input into how to flush this system and get things shifting correctly? Thanks in advance for all the help!

      2021 Axis 750 crew having shifting issue and found milky oil
      By BMurph
      Hi everyone. I am new here to the forum and am excited to learn from all of you with more experience than me with UTVs. Our Axis750 we use on the hobby farm started to have some issues going into gear. Yes, foot is on the brake and completely stopped as required with these machines. I thought it was the linkage and adjusted it to where it is accurately shifting with the engine off and key in the on position. I start the engine and it won't shift gears (yes foot is on the brake). I thought maybe it was the shift lever teeth so I opened the assembly and this picture shows what I just found. I assume this means the wet clutch would need replaced too while draining and flushing the oil. What else should I consider or be looking at? Any idea what could cause this? I don't see visible leaks or cracks in the system anywhere. Thanks in advance for the help!

      2019 750 Challenger won't start...
      By JDawg
      Was using the machine all day to haul wood...no issues until the end...
      When I try to start it, the dash lights come on but starter does not...seems like no power to the starter.
      It is in park, but when I put the brake on to start, it registers N.
      Won't start in neutral either...
      Tried rocking it, did not help...
      Help...

      2023 t-boss 550 belt slipping and found oil in belt housing
      By Cory J
      Belt started slipping when I used it in high gear. It works okay in low unless I'm trying to power it up a hill and then it slips.., Ordered a new belt and went to change it and found a good bit of oil in the belt housing. Has anyone experienced this? Belt looks fine. Only have 300 miles on this thing..
